DETROIT — Fernando Rodney has fired his last arrow in a Twins uniform.

The well-traveled closer became the latest Twins veteran to be dealt Thursday night, landing with the surprising Oakland A’s for Class A right-hander Dakota Chalmers.

According to a person with direct knowledge, Rodney was claimed off waivers, meaning the Twins would not have been able to trade him for the remainder of the season had they chosen to pull him back after the 48-hour period. The A’s will assume all $1.19 million that remains on the 41-year-old Rodney’s contract, plus a $250,000 buyout provision on a $4.25 million bonus for 2019.

Rodney, the active saves leader by one over Boston Red Sox right-hander Craig Kimbrel, recorded his 325th career save Tuesday night in Cleveland. That gave him 25 this season in 31 chances, leaving him five shy of surpassing Francisco Cordero for most career saves by a Dominican-born closer.

Rodney also joined Kimbrel and Kenley Jansen of the Los Angeles Dodgers as the only closers with seven or more seasons of 25-plus saves over the past decade.

“I’m very proud of the job I’ve been doing in my career,” Rodney said. “Every number I’ve been putting up, every number I keep putting in the books, they make me feel happy and proud of the job I’ve been doing. I’ve been working hard in my career.”

Rodney had already pocketed one of five $300,000 bonuses for games finished and needs to finish one more game to reach the next bonus plateau. The A’s would be responsible for those payments as well.

Chalmers, 21, is out for the season after undergoing Tommy John surgery in April. A third-round pick out of a Georgia high school in 2015, Chalmers received an above-slot signing bonus of $1.2 million due to his mid-90s fastball and starter’s frame and pitch mix.

Current Twins pitching coach Garvin Alston, who spent most of the past decade working in the A’s system, would know Chalmers from his former role. Before struggling with injuries and command issues (6.8 career walks per nine innings), Chalmers was rated among the A’s top 20 prospects.

Right-hander Tyler Duffey will be called up to take Rodney’s place in the Twins’ bullpen, according to a person with direct knowledge. Duffey, a former stalwart in the Twins’ rotation, has a 2.72 earned-run average and 55 strikeouts in 53 relief innings for Triple-A Rochester this season.

Rodney becomes the third relief pitcher traded by the Twins in the past two weeks, joining pending free-agent lefty Zach Duke (Mariners) and arbitration-controlled right-hander Ryan Pressly (Astros). The Twins also traded pending free agents Brian Dozier (Dodgers), Eduardo Escobar (Diamondbacks) and Lance Lynn (Yankees) as they seek to reload for another run at the Cleveland Indians atop the American League Central in 2019.

This week Baseball America rated the Twins’ farm system as the seventh-best out of 30 big-league organizations, up from 12th before the season and 22nd less than 18 months ago.

The A’s will mark Rodney’s 10th different team in a 16-year big-league career. When he surprisingly stayed put at the July 31 non-waiver trade deadline, Rodney told the Pioneer Press he hoped the Twins would pick up his affordable option for his age-42 season in 2019.

“I’d love to stay here,” Rodney said. “I think it’s a good young team with a lot of talent. At any moment, any hour, one season this can be the surprise team that wins the division.”

Rodney, who was hitting 97 mph with his fastball in recent outings, said he definitely plans to pitch next season.

“I feel like I can pitch one more year as strong as I feel right now,” he said.

With Rodney out of the picture, the Twins could give save opportunities to sidewinder Trevor Hildenberger or possibly Tommy John survivors Trevor May and Matt Magill. Hildenberger piled up 52 saves during his four-year rise through the minors.

They also have struggling right-hander Addison Reed, who recently spent time on the disabled list with an elbow impingement, under contract for 2019 at $8.5 million. Reed has three 25-save seasons on his resume.
